Tool-Z whom it may concern Be it :known that I, MELVIN 1L. "MUNGER,

.residing at present at Pittsburgh, in the county of AlleghenyandStateof Pennsyl- Vania, have invented certain new and useful Improvements inTire-Vulcanizers, of which the followmg 1s aspecification.

Myinventionrelates to the art of rubber tire manufacture andrepair andit primarily has for its ob ectto providean improved apparatus .forthepurpose wherein is provided a furnace orheat generator :having avulcanizing chamber member that .has provi- S1011 for effectivec1rculat1on ofheat tonbrmg .the sand around the tire;to the proper .and

uniform temperature to vulcanize the .rubber, means being provided forregulat ng and directing the heat for uniform d1str1butionandapplication and means .alsobeing provided whereby tires ofvarioussizesmay be vulcanized on their rims, Meansare also provided forgenerating steam .for producing the necessary moisture to permeate :the

Another object of the invention is. to provide a vulcanizer of asimpleand inexpensive structure which can bemanufactured .at a. minimumexpense and will effectively serve its intended purpose. Y I

The'invention also includes those .novel details of construction,combination .and ar- .rangement :of parts all of which will be :firstdescribed, then be specifically pointed out in the appended claims andillustrated in. the

accompanying drawings, in which:

housing and grate, the partition -,member shown; in Flg; 5 beingremoved.v

Fig. .9 is a detail sectional perspective view .of .the combined cover..for ,the water ,cham- .berand support .forthetirerim.

Beferringnowtothe accompanying drawings, ;1n .which like numerals andletters of ref rence indicate :like parts in all of the figures, '1.representsl the :housing which .has .a'p'air of vertical v walls 2extending from an opening in the .walls of ;the housing ,1 that is.closable bya .door 11, the walls 2 :being locatedto form the sides of.the fur nace or combustion chamber in which .the grate 3 ,is' lo cated,.the housing having a bottom 4:;beneath1theg1iate 3, as fshownin Figs.-1 and 6. I I

5 ,is-a chimney .box that communicates with. thejinterior ofthehousingat. twolevels .through the lower opening '7 and the up- .per, open ng 8,the lower opening 7 i being in alinementwith; thecombllstion chamber and-9 whicln'whenin;the'position shown in .full

lines .in Fig.1, en'ables the-heat ,to pass through the circulatingpassagesand out into .the chimney box-at it's. top :fromwhence. it. es--.-capes through the opening ,6. -.When the gate 19 is raised, however,.1 to, close the opening.8,.the opening-7 .cangbe brought into registerwith. the ichimneyrboxo so that the products, of combustion rand heatmay pass through the opening .-7 directly into. the chimneybox.,Theigate 9Jopera'tesin ways .10.. shown in Fig. 4.

The partition. and chamberj forming member; is preferably constructed asa' unit. and .is indicated inig. 5. .Iteonsists oftlie bottom. plate.12.above the combustion chamber,, the plate 12 having a. portion removed.at 13to'1eave apassage .14 at.tl1e rear0f the; combustionChillllbBlgfOI the products of combustion and heat to passup .abovetheplateL-Q. 17isanintermediate plate located -.a predetermined distanceabove ,the' plate .;12.and-. a1so formingjaa horizontal. partition in,the-ghousing 1,,theiend of that partition ;,Opposite the opening 14:is. removed, as at 18,

sothat the products ofgcombnstion can pass a the horizontal. ring plate2.

' 15 is avertical .annularwall connecting the rim 26 of the tire'isadapted to lie, as is '17 and 19 is a" vertical annular partition thatconnects the plate 18 with the plate 20 so as to form an interiorvulcanizing chamber and spaced sufficiently from the walll to. leave anexterior .heat circulating passage.

It will benotedthat the" diameter of the annular wall 19 is considerablygreater than.

that of the wall 15. v

21 is a combined lid or cover for the water chamber 16 and support forthe tire to be vulcanized. It has a corrugated bottom to allow steamescape beneath the bottom in a radial or fan-like form and it also has acentral steam escape aperture 21 adapted to be governed more or less bya slide 25. The cover also has a vertical upstanding annular rim 22 andan inturned flange 23 on which best shown in Figs. 1 and 3 of thedrawings.

'27 is an annular ring adapted to be laid on the rim 26 and to receive acap plate 28 which is also of ring form, 6., provided with a centralopening for the escape of steam and access to the interior space formedby the ring 27, rim 26 and flange 22. The chamber inclosed by the wall19, plate 28, ring 27, rim 26 and flange 22 forms the vulcanizing boxproper in which sand is placed and acked around the tire according tothe usual practice, and as best shown in Figs. 1 and 3 of the drawings.The plate 28 has openings 29 at intervals so that a thermometer (seeFig. 3) may be inserted to determine the temperature of the sand box atdifferent places around the circle. If it is found that the temperatureis not even, 71.0., too hot or too cool, on one side or the other, thetemperature can be regulated by use of the gates 323 which areinsertible through slots 31 and 33 respect-ively'in the wall 1, the gate32 being insertible at either side of the passageway 14 in the firstlevel of the circulating passage so that, if desired, the heat can beentirely out off against circulation or can be cut off to a greater orless extent accordingly as to whether the gates 32 are inserted theirfull distance or not. If it is desired to permit the heat to circulatein the lower circulating level but not in the upper level, the

' gates 34 are employed to close the passage to the upper level.

It should be understood that in practice the rings 27 and the covers 21with their flanges 22 are made in different sizes to fit the differentdiameter rims of the tires and, in practice, when it is desired tovulcanize a -tire the water is placed in the water compartment 16, thecover 21 of the required "diameter is put on; after which, the tire,mounted on its rim, is'laid into place and sand packed down under thetire; after which. the ring 27 is put into place and addithe sand box.

tional sand packed on top to the required depth, when the plate 28 isput on to close The gates 32 and 31 are opened'and the gate 9 is adaptedto permit the opening 8 to register with the chimney box. Heat thenpasses from the combustion chamber through the opening 14: into thelower circulating level around the water box 16 to the diametricallyoppositeend of its level where it passes up through the opening left bythe removed part 18 of the partition plate 17, to the upper level andfrom thence around to the wall. 19 and escapes through the opening 8. Iftoo much heat is passing to one side or the other, the gates 32 and 3 1are adjusted to compensate therefor. After the required temperature ofthe sand box has been reached the opening 8 is closed and the opening 7is brought into communication with the chimney box so that the heat andproducts of combustion can then pass directly into the chimney box; onlyso much of the heat pocketing above in the circulating passages as .maybe required to keep the sand box at the particular temperature desired.

From the foregoing description, taken in connection wlth theaccompanying drawings, it is thought the complete construction,operation and advantages of my invention will be readily understood bythose skilled -water reservoir communicates, means whereby a circulationof heat may be created from the generating chamber u between the lowerand intermediate walls aroundthe water reservoir and up between theintermediate wall and the top ring around the vulcanizing chamber, saidhousing having a heat escape port from the heat generating chamber tothechimney box and another port from the space above the intermediatewall to the chimney box, and a gate for controlling said ports 2.
